Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Epinephrine improves memory by increasing amygdala activation, which increases cholinergic neuron activation; blocking epinephrine binding in the amygdala eliminates the improvement. → Lauren Margulieux 2025

q2 · i? · review · r2

Conceptual review attributing this mechanism to Cahill and McGaugh's pharmacological work and its reversal: "When epinephrine is high but pharmacologically blocked from binding to receptors in the amygdala, learning does not improve". No education-context data reported.

"Cahill and McGaugh (1998) demonstrated that epinephrine improves memory by increasing activation of the amygdala. In turn, the amygdala increases activation of cholinergic neurons, which improves memory formation"
